I cannot say enough good things about this company & I'm very happy with my new windows. The window installers went above and beyond to make sure my windows worked, were installed correctly, & my sales rep Tom was also very helpful. I don't think I could have gotten better quality windows or service anywhere else. I highly recommend getting your window installation through Smart Windows you wont regret it ?? ??

Terry and his fabulous crew worked with us to make two stunning, huge, glamorous, insulated, custom garden windows. They even installed them for me on Valentines day. I loved them so much, I asked them to put energy efficient windows in the rest of the house. They are gorgeous! Our house is so toasty on those cold, windy nights! The crew were so professional, skilled and cleaned up perfectly. The windows are so easy to operate! You will love Terry and his crew!

We replaced all of our windows with Smart Windows this year and are very happy with the result. The cost was reasonable. Terry and team spent a lot of time with us answering our questions and helping us to draw up a plan. The installation was done in a very professional manner with great attention to detail. We would recommend Smart Windows to others and hope to use them again ourselves next year to replace our front door.

Terry was very knowledgeable about windows and screens. He help my wife and I better understand windows and what options we had within our budget. He had a lot of information and was very detailed.
The installation team did a great job with the windows, enlarging 3 of them up to current residential code. We can open the sliding door with one finger now!
They were fast and efficient, respectful and very pleasant to do business with.
The new windows look great but I was most surprised by how much sound was getting in our home. It is so much more peaceful inside now. At least until the kids get home from school…
